Dr. Weaver is a candidate for the chief of the ER and Dr. Greene is on the selection committee. Much to Weaver's objections, Dr. Ross gets the job as the new pediatric ER attending physician. Although she is book-smart, Lucy continues to hide her incompetence with basic procedures, such as putting an IV into a patient, from Dr. Carter. Having discovered that his son, Reese, is deaf, Dr. Benton continues to keep it a secret. But when Corday suspects that Benton is rekindling his relationship with Carla, he tells her the truth about his son. Greene and Hathaway risk their lives to treat a man who wired himself as a human bomb.
